UPDATE: Reader Bayard Rucker notes that even in orderly Canada (which, of course, lacks any Second Amendment tradition) the rifle registry was a failure: “Not everyone complied. An estimated 65% of firearms owners registered at least one rifle or shotgun, and no more than half of all long guns ended up in the registry. Opposition was intense and has never abated. Grassroots anger helped to fuel the rise of the Reform Party, and contributed to the elimination of the Liberals as a political force in the West.”
